RE: duplicate entry in DB (not the ACID problem)

["Briggs, Bruce" <Bruce.Briggs () suny edu>]

Are they for the same sensor ID?
If so, possibly something is reflecting these packets back out on your
monitored Ethernet segment again.
One way this could happen is from a router/routing switch which gets
these packets forwarded in from some other device and then the router
forwards those packets back out onto the same Ethernet segment.

Subject: [Snort-users] duplicate entry in DB (not the ACID problem)

This is really devastating. I have received multiple identicle entries
of the same event in the DB. These identicle entries has the same pay
load, same src/dest ip, exact same time etc. The only difference is the
event ID. This is not the duplicate key entry error in ACID. I have
about 90% of my alerts receiving multiple entries, and I can't find any
common grounds among alerts receiving multiple entries vs unique entry.
I have also make sure only 1 instance of Snort is running on my sensor.
Any suggestion would be appreciated.
